Both have the same drawbacks (CA, barrel distortion, ghosting), so neither has an edge there.

I dont like the barrel distortion at 10mm which kinda goes away at 12mm

(See attached bedroom picture.)It took me a little longer to notice the next drawback, but reviewing my photos after shoots, I was seeing that the lens has considerable barrel distortion in certain shots, probably mostly at the wider focal lengths

There's barrel distortion at the wide end but fades towards 18mm

Canon 5D, Canon 20D, 300HS, Hero 3 + Black, Hero 4 BlackI could talk about vignetting, and barrel distortion, and edge to edge sharpness, but the only one I have ever really cared about is Chromatic Aberration which is VERY well controlled on this lens.

This is not worth a star off since it should be expected that a lens this wide has barrel distortion, and the amount this lens has is comparable to other lenses in its class.

Along the same lines as CA, every ultra-wide has some barrel distortion; it’s kind of the point of this type of lens.

CONS: barrel distortion, chromathic aberrations, manual

Barrel distortion is almost non-existent, even at the shortest focal length

Also note that the barrel distortion on a UWA gives a funhouse mirror effect on portraits of people when up close (giant noses).

It has a teensy bit of barrel distortion (cry about it) and the vignetting is pretty heavy at f/4.5 (it's already well controlled at f/5.6)-Performance at 18mm is pretty weak.

You can easily fix vignetting, and a lot of the times, you crop out barrel distortion, so that isn't a big deal to me

There is modest barrel distortion at the wide end that is easily corrected in DPP.

so, the lens came undamaged and I would recommend this lens to any vlogger as it gives a wide angle on an APS-C body and to me that is essential for vloggers

Not as well corrected as I'd like, but it's a cheap way to get into wide angle shooting for your crop sensor bodies.

It performs just as good as, if not better than, the Canon EF 10-22mm for less than half the price

Bought this lens for landscape obviously and I loved the 10mm as it's hard to find anything around that for this cheap

While it's not quite as sharp as I would like, it has decent quality, focuses quickly, and a great price.

I personally don’t consider it a drawback as it can lead to some very creative shots.

Great little lens will worth it better than the L lens for cheaper price L

I just wish I could afford the better lens(s)
